Fajitas

Several days ago I had grilled a flank steak and we had quite a bit left over. Often, I use the meat for sandwiches the next day but I decided to make something we haven't had in a while: Fajitas!
I sliced the onion and the peppers up early in the day so they could have time to marinate in a yummy sauce. When it was time for dinner all I had to do was slice the steak, sauté the pepper mixture, crumble the cheese and warm the tortillas. Oh, and open two beers :-)

1/2 lb grilled flank steak, sliced thinly
3 peppers, red, yellow and green, sliced
1 large onion, sliced
1/2 cup olive oil
2 T Worcestershire Sauce
Juice of one lime
2 garlic cloves, minced
1 T cumin
1 T chili powder
1 t salt
1/4 t pepper
some red pepper flakes
1 t sugar
flour tortillas
sour cream or Greek yogurt
crumbled queso fresco ( or shredded cheddar)
fresh cilantro
Fave hot sauce

In a dish, mix the olive oil, Worcestershire sauce, lime, garlic, cumin, chili powder, salt, pepper, red pepper, and sugar until well combined. In large zip lock, place pepper and onion mixture, pour on sauce and marinate in fridge for several hours.

When ready to serve dinner:  Sauté the pepper mixture the way you like it--some people like the veggies really crispy and others like them more well done. Slice the steak and warm the tortillas. Let everyone build his own adding cheese, fresh cilantro and hot sauce.
